“…Although their study produced estimates of respective physical effects from projected climate data under conditions of socioeconomic scenarios, and evaluated the projected economic effects by the economic model, it has no theoretical consistency between estimates of physical effect terms and economic models. In a general equilibrium analysis of waste problems in Japan, Miyata [5] derived a utility function consistent with a pre-formulated demand function from solving the integrability problem, and integrated externalities such as waste into a CGE model. For the sandy beach loss caused by climate change, Sakamoto and Nakajima [6] and Nakajima and Sakamoto [7] developed a CGE model that has a utility function consistent with a recreation demand function in a travel cost method by solving the integrability problem.…”

To measure economic effects of changes in environmental quality caused by climate change in Japan, we estimate beach loss damage costs in Japan and in each prefecture and evaluate the economic effectiveness of hypothetical adaptation measures to restore sandy beaches. For analyses, we use a computable general equilibrium model (CGE) that integrates a utility function with environmental quality factors as an independent variable derived from a recreation demand function in a travel cost method (TCM). We use future projections of beach loss rates in 2081–2100 based on ensemble-mean regional sea-level rise (SLR) for four Representative Concentration Pathway (RCPs) scenarios (RCP2.6, RCP4.5, RCP6.0, and RCP8.5). The main findings of our study are presented as follows. (1) In 2081–2100, beach loss damage costs were estimated respectively as 398.54 million USD per year for RCP2.6, 468.96 (m.USD/year) for RCP4.5, 494.09 (m.USD/year) for RCP6.0, and 654.63 (m.USD/year) for RCP8.5. (2) For all RCPs, six prefectures for which the cost–benefit ratio exceeds 1.0 were Kanagawa, Osaka, Hyogo, Hiroshima, Saga, and Kumamoto. Our hypothetical adaptation measure of an artificial beach enhancement is expected to be quite effective as a public works project in these prefectures.

“…The second group of models already and explicitly includes waste management and processing. In the three-sector equilibrium model of Miyata (1995), one of the sectors is responsible for processing of waste. Thus the cost of waste management is endogenously determined.…”

“…The paper's intention is the development of a model that explicitly enables the utilization of waste as a raw material, similarly to that of Baumgärtner's (2004) solution, but does so in a general equilibrium framework that endogenously includes the price of waste management, as in Miyata's (1995) model. This study introduces and applies a modelling system that is suitable for the impact assessment of environmental innovations referred to as "Blue Economy" innovations.…”

This study introduces and applies a modelling system that is suitable for the impact assessment of environmental innovations referred to as "Blue Economy" innovations. The paper's contribution to the literature is threefold. First, the building of a multi-sector computable general equilibrium (CGE) model, which provides the theoretical framework for studying the economic impacts of using waste as a production input. Second, the creation of an empirical methodology through which new Blue Economy technologies can be concretely accounted for in regional input-output tables. Since Blue Economy innovations are mostly built on local inputs, their effects are primarily local. Third, given that interregional spillovers of local impacts might also be significant, through interregional trade or migration, a modelling approach that can follow complex spatial processes is applied. The broader model framework chosen is the GMR-Europe model.

“…The second group of models already explicitly includes waste management and processing. In the three sector equilibrium model of [3] one of the sectors is responsible for processing of waste, thus the cost of waste management is endogenously determined. Speck [4] introduces a six "sector" model where four sectors describe the technologies optionally available for the economy, the fifth sector can be interpreted as waste management that reduces environmental pollution, while the sixth sector catches the waste decomposer capability of nature.…”

This paper introduces and applies a model system that is suitable for the impact assessment of Blue Economy innovations. Our contribution to the literature is threefold. First, we build a multi-sector computable general equilibrium (CGE) model, which provides the theoretical frame for studying the economic impacts of using waste as a production input. Second, we create an empirical methodology through which new technologies of Blue Economy can be concretely accounted for in regional input-output tables. Since Blue Economy innovations are largely built on local inputs, their effects are primarily local. Given that interregional spillovers of local impacts might also be significant, through interregional trade or migration, we applied a modelling approach that is able to follow complex spatial processes. The broader model framework chosen is the GMR-Europe model.
